The initial concept, by Allseas technical director W.P. Kaldenbach, was of a vessel capable of lifting entire platforms, and in 1987 Allseas declared its intention to build it. The initial idea featured two rigidly connected, self-propelled supertankers, with a large slot at the bows enabling it to install platform topsides in one piece. Early designs featured a flotation and ballasting system and active motion compensation system to facilitate a controlled transfer of a topsides’ weight from the vessel to a platform substructure. Allseas developed the original idea to include steel jacket installation, jackets and topsides removal and rigid pipelay capabilities.

Near the stern, about halfway down the starboard topsides, was a rounded wooden block about in diameter and high, with a central hole for a rope. This corresponded to a hole in the midsection of the rudder blade. From the outside the rope ran through the blade, through the round block and topsides and was fastened inside the hull. The flexibility of the hemp rope allowed the blade to pivot.

The majority of the construction was performed at a site in Bull Arm, Trinity Bay, Newfoundland and Labrador. A new community housing 3,500 workers was constructed, with its own cafeteria, gym and entertainment facilities. Many of the topsides modules were constructed locally, with some sourced internationally. The 550,000-ton slipform concrete GBS was built inside a drydock and mated with the topsides in the nearby deepwater construction site.

This became popular with the US Navy in particular and they used it during the War of 1812. Vessels were of oiled wood except for the wale, the widest strake that rubbed other vessels, docks, etc. Wales were tarred or otherwise blackened; as they had been from Greek and Roman times. Topsides were maintained by scraping and re-applying oil.

At the bow the cut water was especially strong, as longboats sailed in ice strewn water in spring. Hulls up to wide gave stability, making the longship less likely to tip when sailed. The greater beam provided more moment of leverage by placing the crew or any other mobile weight on the windward side. Oceangoing longships had higher topsides about a high to keep out water.
|
|
The other two topsides named P1 and LQ were installed in March 2019. This set a new record with P1 topside weighing 26,000 tons is the heaviest single-lift executed offshore till date. The vessel is expected to return in 2022 to install P2 topside weighing 27,000 tons for phase two of the Johan Sverdrup development. It removed Valhall QP topside for Aker BP in June 2019.

In boat and ship construction, strakes immediately adjacent to either side of the keel are known as the garboard strakes or A strakes. The next two are the first broad or B strake and second broad or C strake. Working upward come the bottom strakes, lowers, bilge strakes, topside strakes, and uppers also named sequentially as the D strake, E strake, etc. The uppermost along the topsides is called the sheer strake.

Like dories, sharpies are initially tender since they have a shallow draft without a keel. They need large amounts of ballast stowed on the central floor before they become acceptable as sea boats: 600 to 900 lbs is normal in a 30 ft boat. Sharpies rely on their high flared topsides to provide stability when heeled on a reach or to windward. The twin unstayed masts makes rigging very easy and saves on cost.

The Sutton Hoo longship, sometimes referred to as the ghost ship of the Wulflings, is about maximum beam and built about 625 AD. It is associated with the Saxons. The ship was crushed by the weight of soil when buried but most details have been reconstructed. The ship was similar in hull section to the Nydam ship with flared topsides. Compared to later longships, the oak planks are wide—about including laps, with less taper at bow and stern.

A more recent development is concrete sub-sea structures. Concrete offshore structures show an excellent performance. They are highly durable, constructed of almost maintenance-free material, suitable for harsh and/or arctic environment (like ice and seismic regions), can carry heavy topsides, often offer storage capacities, are suitable for soft grounds and are very economical for water depths larger than 150m. Most gravity-type platforms need no additional fixing because of their large foundation dimensions and extremely high weight.

Goldeneye Gas Platform is an unmanned and now abandoned offshore gas production platform in North Sea block 14/29, in the South Halibut basin area of the outer Moray Firth, 105 km northeast of St Fergus Gas Plant in Scotland. The topsides were designed by SLP Engineering Ltd. Production was from five wells with well fluids separated by a single vertical separator vessel. Separated liquids were re-injected into the export gas stream without further treatment.
|
|
Formal cessation of production for the Miller field was approved by the DECC in September 2007. In 2009, BP estimated the gross cost of decommissioning the field to be of the order of £300 million. The initial phase of decommissioning activities involving well abandonment and topsides cleanup were completed by the end of 2009. The oil and gas export pipelines have been flushed clear of hydrocarbons and are being left in place for potential future use.

The Aasta Hansteen spar was built on its side in the dry dock on barges. Once built it was floated off the barges and then floated onto the heavy transport ship Dockwise Vanguard and shipped to a fjord near Stord in Western Norway. The spar was upended in the fjord, after which the topsides were installed using the floatover technique. It was then towed vertically to the Aasta Hansteen gas field 300 km off Bodø at the northwest coast of Norway.
|
|
Originally called the Luva gas field and later renamed after Aasta Hansteen, it was discovered in 1997 approximately 300 km off the coast of Norway. During start up of the platform, the production from the surrounding Luva, Haklang and Snefrid gas fields will be exported to the platform. Future fields already discovered are planned to be tied back to the Aasta Hansteen platform through SCRs. Future expansion of additional risers and topsides facility are built-in in the design of the platform.

On platforms this technology can be applied to perform modifications, maintenance upgrades, to remove crane pedestals, compressors and topsides, and for hurricane remediation. Sub-sea saws can be installed by divers while being monitored and powered from a barge or platform, or they can be installed and powered by working class ROVs. The robust characteristics of these four wheel drive bespoke underwater wire saws, combined with remote control functionality, makes them suitable to extreme offshore decommissioning conditions such as the North Sea.

Flared bow of a cruise ship A ship's bow should be designed to enable the hull to pass efficiently through the water. Bow shapes vary according to the speed of the boat, the seas or waterways being navigated, and the vessel's function. Where sea conditions are likely to promote pitching, it is useful if the bow provides reserve buoyancy; a flared bow (a raked stem with flared topsides) is ideal to reduce the amount of water shipped over the bow.Note: Aside from making the deck slippery, salt water may corrode metal decks.

Early designs of the 1920s were often built by amateurs, who employed the lightest materials available to them at the time, which were often glued timber boarding or plywood on the floor, plywood topsides, and varnished canvas decks. Most were about long and stepped hulls were employed with a step to induce air under the hull, to enable the boat to float on air bubbles. The principle behind 'planing' was not fully understood. Thus, hulls were flat bottomed with an upward curve at the bow and the step of the way aft.

The Playmate was a wooden lapstrake rounded-bottom hull with all models built in 1935 and later powered by a Buchanan Midget 25-horsepower inboard engine. The boat was redesigned in 1939 with forward seats and a windshield, along with a slightly higher hull, which was the configuration it retained for the rest of the production run. In 1940 Duke introduced two larger launches; 19 and 21 feet long, with cedar lapstrake bottoms and mahogany topsides and decks. The smaller models were powered by a 4-cylinder Buchanan 57-horsepower or Gray 75-horsepower engine.

The shape suggests mainly river use. Unlike later boats, it had a low bow and stern. A distinctive feature is the two- prong cutaway bow section. Stora Hammars I stone, Sweden showing armed warriors in a longship The first true longship that was rowed was the Nydam ship, built in Denmark around 350 AD. It also had very rounded underwater sections but had more pronounced flare in the topsides, giving it more stability as well as keeping more water out of the boat at speed or in waves.

Boadicea was one of a batch of large frigates ordered in 1795, all of which were the largest of their type, and the majority of which were to the draught of captured French ships. She was built to the design of , a 40-gun ship completed in 1787 and captured in October 1793. Changes were made to the shape of the topsides, and the scantlings and fastenings were strengthened to reflect British practice. She retained her shallow French hull form, and as a result the holds and magazines were considered cramped.

The topsides were designed by McDermot Engineering. The plant had a capacity of 50,000 barrels of oil per day and 30,000 barrels of produced water per day. The plant comprised two parallel 3-phase (oil, gas and produced water) first stage separators operating at a pressure of 440 kPa and a common 3-phase second stage separator operating at a pressure of 241 kPa. Oil shipping pumps with a capacity of 55,000 barrels per day delivered oil to the export pipeline to the Cormorant A installation at a pressure of 3447 kPa.

Pioneering Spirit set a new offshore lift record with the single-lift removal of Shell's 24,200 t Brent Delta topsides in April 2017. For its first commercial job, the vessel removed the 13,500 t Yme mobile offshore production unit from Norwegian waters for Repsol in August 2016. Pioneering Spirit’s started its first pipelay job, installation of the offshore section of the TurkStream pipeline in the Black Sea, in June 2017. Allseas has committed to building an even larger version of the same design, Amazing Grace, which is scheduled to be delivered in 2022.

The Aasta Hansteen platform is a truss spar type allowing condensate to be stored in the hull below sea level and offloaded to a shuttle tanker. The produced gas is exported to the shore with steel catenary risers (SCR). The production risers are also SCRs, with these being the first time SCRs have been used in the Norwegian Sea. The spar hull was designed by Technip, with the topsides being designed by CB&I;, with both being fabricated by Hyundai Heavy Industries in South Korea before being transported to Norway for installation.

While in dock, her entire hull was cleaned, blasted, and repainted, her hull blanking plates inspected and an ultrasonic survey carried out. She is not expected to require further drydocking until 2020. While under tow to Portsmouth she was delayed by bad weather and arrived a day late: it had been intended that she would arrive on 6 June 1999, the fifty-fifth anniversary of the Normandy landings. During the maintenance work, Belfast hull and topsides were repainted in her specific camouflage scheme officially known as Admiralty Disruptive Camouflage Type 25, which she had worn from November 1942 to July 1944.

Heerema booked its first contracts for SSCV Sleipnir in 2017, two years before it was completed. During the ship's maiden voyage from Singapore to Spain via the Cape of Good Hope, it set a world record for the largest LNG bunkering operation on July 10, when of LNG were transferred to it off the coast of Sumatra from Coral Fraseri, chartered by Titan LNG from Anthony Veder. Coral Fraseri was scheduled to refuel Sleipnir in Spain, prior to it passing into the Mediterranean Sea. Sleipnir completed a record lift of for the topsides of the Leviathan project for Noble Energy, in September 2019.

Her topsides were wrecked, and a large fire burned amidships. After firing steadily for over 30 minutes, without any problems, King George V , by 09:27, began having trouble with her main battery, and from that point onward every salvo missed at least one gun due to failures in the safety interlocks for antiflash protection and from ammunition feed jams. At 10:21, with Bismarck silenced and obviously sinking, Admiral Tovey detailed the cruiser to finish her off with torpedoes. King George V fired 339 14 in (354 mm) and over 700 5.25 in (133 mm) shells during the action.

The storage system was decommissioned by Shell from 2005 to 2007 prior to the sale to Fairfield Energy. The topsides facilities included capability to drill, produce, meter and export oil. It also has capability to re-inject water to maintain reservoir pressure, (111,250 bls/day)predicted. Peak production was 115,000 barrels per day in 1979; and it was approximately in the region of 3500 - 4000 bpd in 2015 prior to the shut in announcement (Production ceased on 15 June 2015) Oil production is by pipeline to Cormorant Alpha and then by Brent System pipeline to Sullom Voe, Shetland.

The decommissioned tension-leg platform had been acquired by Sevmorneftegaz in 2002 and its 19,000-tonne topsides had already been transferred to a new ice-resistant production platform being built for the Prirazlomnoye field in the Pechora Sea. While underway to Lerwick for refueling, one of the tow lines connecting the 23,000-tonne platform hull to the two tugboats broke free, but was later reconnected. In the end, the hull was towed to Cromarty Firth where it remains . In August 2011, National Science Foundation (NSF) contracted Vladimir Ignatyuk to support the annual break-in and resupply mission to McMurdo Station in Antarctica.

The A-4P Skyhawk (called A-4B by the Argentines) were bought from the US Navy inventory in 1966 and at the time of the war were painted green/brown topsides with light blue undersides heavily faded colours. Yellows identity markings were also added during the conflict. These aircraft provided outstanding performance and availability even in the harsh operating conditions of the South Atlantic with most of them returning from missions with some form of battle damage and were patched up and pressed back into service within matter of hours. Because of this, pilots used to change airframes between sorties.

The river then skirts Christ Church Meadow before flowing into the Thames (or Isis) through two branches; the island in between has the main shared college boathouses for rowing. Easter and Summer punting is popular on the Oxford stretch. (A punt is a long, flat-bottom, low-topsides, boat propelled by a pole pushed against the river bed.) Punts are typically hired from a punt station by Magdalen Bridge, or the Cherwell Boathouse (just to the north of the University Parks). It is possible to punt all the way from the Isis, north past the University Parks, and out beyond the ring road.

The platform acts as a small concrete island with serrated outer edges designed to counter icebergs. The GBS contains production storage tanks for 1.3 million barrels of oil in an 85 m high caisson, with the entire structure weighing 587,000 tonne before 450,000 tonnes of solid ballast were added.Offshore TechnologyHibernia Construction The GBS was constructed in Bull Arm and the "topsides" production and living quarters was attached to the base while floating in Bull Arm, before the integrated unit (production platform and GBS) was towed out to the actual Hibernia field. Production commenced on November 17, 1997.

The remaining 6-inch breech-loading guns which these vessels carry are fitted at broadside ports in the ordinary way. The Nordenfeld guns are fitted in projecting parts of the topsides, and are so arranged as to give great training and great depression, firing into boats alongside. The Whitehead torpedoes are discharged from broadside ports on the lower deck, two forward and two aft.""Lord Brassey", The Naval Annual, 1886, page 199. When Leander was first commissioned in May 1885, her armament was listed as follows: :"Upper deck 10 6-in BL, 8 1-in Nordenfeld, 2 5-barrel and 2 2-barrel 0.45-in guns.

With considerable labour > two strakes were added to the topsides, formed out of paling's which were on > board, and on the 14th June all was ready for a start. The crew drew lots as > to who should ,go in the boat, and they fell to Captain Geach, the chief > officer, the steward, Mr. Simmens a passenger, and two natives. On 21 June the schooner Joan Andrews under Captain Stewart, while on a run from Rockhampton to Sydney, picked up the crew in the lifeboat and brought them to Sydney. On the evening of 28 June the government vessel Thetis left Sydney for the reef and arrived there late the next day.

Hibernia Gravity Base Structure during construction The Hibernia Gravity Base Structure is an offshore oil platform on the Hibernia oilfield southeast of St. John's, Newfoundland, Canada. A 600-kilotonne gravity base structure (GBS) built after the Ocean Ranger disaster, it sits in of water directly on the floor of the North Atlantic Ocean off St. John's, Newfoundland at . This GBS is designed to resist iceberg forces and supports a topsides weighing 39,000 tonnes at towout, increasing to 58,000 tonnes in operation. There were significant challenges faced by the engineering firms Doris Development Canada, Morrison Hershfield and Mobil Technology in developing a structural solution with adequate strength which was also constructible.

A wreck that is believed to be that of Bristol Packet lies in the intertidal zone on Madbrian sands off Minehead where it has been exposed at different times including between February 2014 and July 2015 when a visual survey was undertaken and the exposed parts of the wreck photographed. The position of the wreck indicates it was driven on its beam ends onto the sands. The date of the vessel is confirmed by comparison of the way it was built of pine and larch, incorporating both treenails and copper fastenings, with other vessels of the same period. Bristol Packet is known to have had pine topsides.

The ship was designed by Pete Culler, a naval architect in the United States, as a working fishing boat with a large engine and a small sailing rig. Tucker Thompson changed her design to build her in steel and extended her by more than two metres, making the hull longer and deeper to accommodate the tall rigging. Her design is based on a halibut schooner and a replica of vessels that plied their trade on the Pacific West Coast of the USA in the early 19th century. The schooner was constructed with a welded steel hull and decking, with topsides and deck overlay made from kwila.

Indeed, it notable sheer further confuses the matter. The Niagara’s high topsides compare to contemporary designs but its coach house hints at the traditional shapes and trim of older designs." A review in Cruising World written by Jayne Finn in 2006, stated, "Traditional looks combined with modern features draw frequent compliments for the Niagara 35 ... Under way, the boat is stable and stiff, and we've had the rail of our Niagara 35, Phantasia II, in the water only once, when beating down Lake Huron in 20 knots of wind. On that same trip we hooted and hollered downwind at over 8 knots on a day on which virtually no one else was out.

Although only six boats contested the 1960 contest at Auckland the regatta was anything but uninteresting. As one leading New Zealand yachting journal said: "The 18s are still the glamour boats with the general public. Even the weekday races saw the waterfront road and headlands thick with spectators and the starting wharf completely packed". There were great dramas even before the racing began when Bob Miller (later famously known as Ben Lexcen) arrived with his radically designed Taipan, which was the biggest break in tradition since the skimmer. She was a three-man boat, hard chine, plywood construction, reverse sheer, half-decked, heavily flared topsides and narrow (4 ft 3in) beam on the chine.

Higher topsides were supported with knees with the long axis fastened to the top of the crossbeams. The hull was waterproofed with animal hair, wool, hemp or moss drenched in pine tar. The ships would be tarred in the autumn and then left in a boathouse over the winter to allow time for the tar to dry. Evidence of small scale domestic tar production dates from between 100 AD and 400 AD. Larger industrial scale tar pits, estimated to be capable of producing up to 300 litres of tar in a single firing have been dated to between 680 AD and 900 AD. A drain plug hole about was drilled in the garboard plank on one side to allow rain water drainage.

The emphasis switched from the conversion of two existing tankers to a new-build hull in 2004, though retaining the catamaran concept. The decision was prompted by a lack of suitable vessels to convert, the lower costs associated with a new-build, and the need to house sophisticated equipment – such as a dynamic positioning system – in the hull. In 2007, twenty years after the idea was first conceived, Allseas announced plans to build the Pieter Schelte, a twin-hulled platform installation / decommissioning and pipelay vessel. Named after the offshore pioneer Pieter Schelte (father of Heerema), the design featured a lifting system at its bows for lifting platform topsides up to and a lifting system at its stern for lifting steel jackets up to .

The Thistle Late Life Extension (LLX) Strategy aims to recover over 35 million barrels of oil over the next 15 years from the Thistle and Deveron oil fields, using a mixture of existing well stock and new wells. A drill rig re-activation project has been completed and has successfully delivered several new wells and well renovations to date with an industry leading-safety record. The Thistle LLX strategy will also ensure that the Thistle platform will be operable to 2025 and beyond. To achieve this, a series of major activities have started including initiatives to provide reliable power, improve structural and topsides integrity, upgrade safety and control systems and simplify the platform oil and production and water treatment processes.

To ensure that strength is not compromised by this weight savings approach, Kadey-Krogen uses massive stem-to-stern fiberglass girders that are closely spaced for effective distribution of hull loads to bulkheads, and encapsulated mahogany girder inserts that allow equipment to be attached for maximum strength and reliability. Cast lead (as opposed to iron) ballast conforms to the keel contour and is concentrated low in the hull so less ballast material is required and weight is reduced. Deckhouse and hull topsides are of cored laminates for reduced weight, lower center of gravity, thermal insulation and strength. Critical areas are reinforced with an impact-resistant fiberglass mat containing Twaron, which is the same fiber used to give body armor "bullet-proof" capability.

RNLI inshore rescue boat during Falmouth Lifeboat Day, August 2006 A rigid inflatable boat (RIB), also rigid-hull inflatable boat or rigid-hulled inflatable boat (RHIB), is a lightweight but high-performance and high- capacity unsinkable boat constructed with a rigid hull bottom joined to side- forming air tubes that are inflated with air to a high pressure so as to give the sides resilient rigidity along the boat’s topsides. The design is stable, light, fast and seaworthy. The inflated collar acts as a life jacket, ensuring that the vessel retains its buoyancy, even if the boat is taking on water. The RIB is an evolutionary development of the inflatable boat with a rubberized fabric bottom that is stiffened with flat boards within the collar to form the deck or floor of the boat.

In a local news article, Hillard Bloom of Tallmadge Brothers explained that the vessel should not have been hauled and left on dry land as it had, if there were intentions of ever making it a working vessel again. He stated that the planks of oak vessels like Hope have the tendency to shrink when removed from the water for an extended period of time. The restoration process began with Hope being lifted back into the water where its boards were given the opportunity to take in moisture and expand. The restoration process continued when the crew of Tallmadge Brothers transported the vessel to a dry dock in Bridgeport, CT where its boards were caulked, its deck was sanded, its mast was stepped, its bottom and topsides were painted, and it was fully rigged.

She was acquired from the company by the California Pacific Railroad Company in 1871. Amelia (sidewheel steamer): She was launched in 1863 originally as a San Francisco Bay ferry, running between Alviso and San Francisco. In 1868, Amelia was one of the first steamers in the Bay Area to convert from coal to oil for fuel. She was acquired from the company by the California Pacific Railroad Company in 1871. American Eagle: She was one of the original ships consolidated into the company in 1854, The ship was damaged in a boiler explosion and thereafter lay moored on the levee in Sacramento for several years. In 1859 her topsides were removed and she was converted into a barge. Anna Abernethy (sidewheel steamer): She ran as a competitor to the company on the Marysville - San Francisco route beginning in 1854.

The new resin was designed to be fire retardant, and was originally developed to the specifications of the US military late in the Vietnam War. It is widely suspected that the new resin was responsible for extensive non-osmotic blistering of the hulls, deck, and cabin-house structures in boats built between 1976-1981. Many of the "blister boats" were "repaired" by stripping the outer layers of fiberglas off the exterior of the hull (either undersides and topsides, or just undersides below the water line). The repair then involved drying out the stripped hull for several months (commonly in the California or Mexico desert), followed by reglassing the exterior with several layers of fiberglas with vinylester resin or polyester resin. However many of the blisters have returned on "blister boats" (hull Nos 120 to 249) despite major repairs.

Allseas was founded in January 1985 by Edward Heerema, son of the late Pieter Schelte Heerema, founder of the Dutch offshore construction and installation company Heerema Marine Contractors. Offices subsequently opened in The Hague (the Netherlands) and Châtel-Saint-Denis (Switzerland). The company spent its early days developing the concept of dynamically positioned (DP) subsea pipelay. Allseas acquired the former bulk carrier “Natalie Bolten” in 1985 and converted it for DP pipelay at the Boele shipyard in Bolnes, the Netherlands. The vessel was christened Lorelay in Rotterdam on 26 April 1986. Lorelay immediately entered service and successfully executed her first pipelay contract, the 8-inch, 1.8-km Helder A-B pipeline, for Unocal in the Dutch sector of the North Sea. In 1987, the company declared its intention to build a vessel capable of lifting entire offshore platforms. The initial idea featured two rigidly connected, self-propelled supertankers, with a large slot at the bows to install platform topsides in one piece. During the late 1980s and early 1990s, the company established itself a major player in the North Sea and Gulf of Mexico. In 1992, the company acquired the former bulkhead carrier “Trenchwood” for conversion to Solitaire, the world's largest pipelay vessel.
