Jumbo Javelin and Fairpartner
Jumbo is currently building two new-generation super heavy lift vessels in response to the offshore industry’s demand for a higher lifting capability as well as a larger outreach and lifting height for offshore installation. Designated as J-1600 class ships, these two 11,000dwt units, the MVs Jumbo Javelin and Fairpartner will be the most powerful heavy lift cargo vessels in their class in the world.
They were built at the Damen Shipyards, Galatz. The vessels will be managed by Jumbo with Rotterdam-based Kahn Scheepvaart acting as agents and Gard Arendal appointed as the P and I club.
They are scheduled to be taken into service as from first quarter 2004. These eighth-generation Jumbo heavy lift ships are designed to provide new heavy transport solutions for its core markets which includes the oil and gas sector – both onshore and offshore – and wind power generation industries.
The vessels have an overall length of 143.1m and a breadth of 26.5m. There is an air draft above the keel of 46.40m (derricks down). The main deck is completely flush, with a width of 26.5m. The deck can accommodate large topside process modules as its width can be extended to nearly 40m using ‘fly-decks’. The vessel has a gross tonnage of 15,069t and a 3,768t net tonnage. It registers a deadweight of 7,750t or 10,975t including derricks etc.
The vessels have one hold, accessed by a single hatch. This hold has a capacity of 19,500m³. The lower hold measures 82.7m x 17m and the tweendeck measures 101.9m x 17m. For an optimum underdeck stowage configuration, each tweendeck pontoon is variable in height and standard underdeck height can be extended from 12.5m to 15m.
To support the cargo, the vessels have a tank-top strength of 12t/m² and the strength of the tweendeck is 7t/m². Three hatch-covers have a strength of 12t/m² and five have a strength of 8t/m².
The super heavy lift new-buildings feature two state-of-the-art rotating mast cranes with a combined lift capacity of 1,600t at a maximum outreach of 28m. For highly efficient general cargo handling, the main hoists are supplemented with a range of other handling systems. The auxilliary hoist has a 35t travelling trolley and there is a 10t whiphoist.
With a shallow draft of just 6.5m, the J-1600 class retains the small port operational capability that Jumbo’s fleet is renowned for.
In order to increase operational flexibility, the deckhouse and bridge are placed forward and only extend across half the deck-width. This solution maximises longitudinal deck space, allowing for the comfortable accommodation of reactor columns which can exceed 150m in length.
The vessels are powered by two main engines, rated at 4.320kW. The engines are MAN 9L 32/40 units which provide for speeds of up to 17.5 knots. The engines use up to 37t of fuel per day at a continuous rate of 90%. When in harbour, the vessels consume up to 3t of heavy fuel oil or 1t of gasoil per day. For manoeuvring in port, the vessels have Lips bow thrusters. The vessels have bunker capacity for 1,200t of heavy fuel oil and 100t of gasoil. Fresh water capacity is 150t.
The Dutch-flagged vessel is classified by Lloyds with the notation 100 A1, LI, CG, +LMC, UMS, with descriptive note SCM regarding loading and unloading.
