To m ee t the inc rea sing demand for oil worldwide, the rap id build ing of ves-sels, capab le of deepwater offshore operations, is req uired to rep lac e exist-

ing , obsolete offshore vessels. GPA s vessel designs are b ased on efficiencyand constructability:

GPA 254L AHTSA State-of-the-Art Anchor Handling Tug Supply Vessel.

Anc hor Hand ling and TowingThe GPA 254L AHTS is eq uipp ed with a Ma c -Gregor-Plimsoll doub le d rum winc h rate d a t150 mt line p ull on eac h d rum for towing a nd anc hor hand ling op erations respec tively. Thevessel is eq uipped with a 250mt Ste rn Roller, Sha rk Jaw s for the safe stopp ing o f cha ins andwires during anc hor hand ling op erat ions, Ret rac tab le Tow ing Pins for centering , controllingand guiding to wing line a nd cables tow ing o pe ra tions.

+30% Grea ter Cargo Capac ityThe engine room has bee n moved to a bo ve ma in deck, a c oncep t pioneered by GPAseveral yea rs ago. This unique p ropulsion c onfiguration creates greater cargo capacitiesbelow dec k as the d rive sha ft has been e liminated . Com pared to trad itional AHTS vesselsof simila r size, the GPA 254L AHTS c an therefore c arry 30% more c argo.

Fuel Savings

The Diesel-Elec tric Propulsion system is environmenta lly friend ly by dec reasing CO 2 em is-sions by 30% and also offers improved fuel effic ienc y. Clients benefit from considerablecost savings, as the insta lla tion of d iesel generators of d ifferent o utp ut ratings can p rovidesma ller inc rem ents of pow er to best suit a g iven op erationa l mode. Add itional elec tricconsumers can be a dded to the design, suc h as add itiona l thrusters or Fi-Fi pumps withoutad ding ded ica ted d iesel engines to d rive them .

Reliab ility and Excep tiona l Maneuverab ility in Ad verse ConditionsThe GPA 254L AHTS is equipped with two azimuthing ste rn thruste rs, one fixed ste rn thrusterand two bo w thrusters, whic h a llow excep tiona l maneuverab ility and sta tion-keep ing ca-pab ilities. The Dynam ic Positioning system Class II c rea tes dua l red und anc y on a ll eq uip-

ment a nd ena b les the vessel to ma inta in p rec ise position when a long side rigs or plat formsto offloa d c argo , if and when req uired , even in adverse w ea ther cond itions. The sta tion-keeping capability also improves the Anchor Handling process due to less tension on wire,inc rea sed safety fo r the d ec k crew , prec ise sta tion-keep ing and a lso a llow s the vessel tomaintain forward p osition in sea wa y. This unique p rop ulsion configuration permits the ves-sel to c a rry out op erations sa fely and makes vessel mo re reliab le.
