New record with 5000mt Offshore Mast Crane order
Nordic Heavy Lift subsidiary Avonway has ordered a unique crane vessel with a record 5,000 tonne single mast lifting capacity with Singapore's Sembawang Shipyard. This means again one of the innovative designs of Dutch based companies Sea of Solutions and Huisman is put into reality. Sea of Solutions (part of Offshore Ship Designers Group) was responsible for both the concept and basic design of this monohull vessel, which has the largest single mast crane ever installed on a vessel. Huisman designed and will construct this 5,000 mt crane. The crane vessel is scheduled to enter service in March 2010.
The design has many innovations but what catches the eye is the enormous single mast crane, reaching approximately 150 metres above the deck when topped up. It will be the largest single mast crane yet built. Until now the largest crane measured 3000 sht for the Sapura 3000, also a combined Sea of Solutions / Huisman project currently under construction. Today's deepwater oilfield construction projects demand high transit speeds and good DP capabilities when on station. The vessel's transit speed of ca. 14 knots is achieved by installing 2 propulsion thrusters of 5.5 MW each. These combined with four 3.2 MW retractable thrusters and a 2.5 MW bow thruster give the vessel DP3 class. Provision for a future 8-point mooring system is built into the design.
Main dimensions of the vessel are: Loa 180.9 m Lpp 170.1 m Beam 46.2 m Depth (moulded) 16.1 m Draft (operational) 7.0 - 11.0 m Installed power 6 x 5,765 kW The 5000mt Offshore Mast Crane is a typical and proven Huisman design, with the following main specifications: Capacity over the stern 5000mt at 34m Capacity revolving 4000mt at 41m Mast height 82m Total boom length 120m Max radius main hoist 79m Max radius aux hoist 109m Max radius whip hoist 122m
