SUMMARY

1.1. Introduction

2. A Submerged Turret Production (STP) buoy which was floating at a depth of 9m had a

270m pick up rope attached to it with the end floating on the surface with a small lighted

buoy attached. A Tug towing the ‘Haewene Brim’ FPSO ran over the rope and got it

entangled in its propellers. Some of the rope from the Tugs props was recovered but not

all of it. There was a danger that there was still some rope attached to the buoy which

could become entangled in other vessels props.

3. It was decided that a vessel would be required to survey the buoy to determine how

much rope, if any was attached to it. A 111m ROV survey vessel the DSV ‘Fugro Saltire’

was hired to take a workboat (W/B) out to the site and use a small ROV hung over-side of

the W/B for the survey. The ROV saw the buoy which had about 7 to 8m of 115mm rope

floating vertically from the buoy. The W/B was then recovered to the ship. The large ROV

vessel then launched its work class WROV and did a more detailed survey of the buoy.

3.1. Work Observed: The Tug that ran over the buoy rope was well inside the 500m zone

(< than 70m) and all of the rope except the bridal was on the tug’s props. The W/B

was launched by the ships main Knuckle boom crane which had the potential of the

load becoming uncontrollable if the mother vessel began rolling (see photo No5). The

W/B handled the seas well (2m) but had some problem finding the buoy. Once located

there was a lot of movement of the ROV due to the workboats movement in the seas.

3.2. Observations: The DSV vessel managed to make a lee for the workboat and also

positioned itself to reduce rolling to a minimum using the DP. The workboat was

launched and recovered without mishap. The Tidal Forces were insignificant. The

main force was the wind 20kts; this caused a lot of drift on the workboat which the

coxswain had to deal with. The DP current was in line with the wind.

3.3. Conclusions: If the workboat had a radar reflector fitted the DSV could have picked

up the boat much easier on its radar. A GPS on the workboat would have helped in

locating the buoy and remaining on station. Due to the professionalism of the project

crew and the ships crane drivers/crew all operations were carried out in a safe and

seamanlike manner. The DSV’s Man Overboard rescue boat was ready throughout.

3.4. This report is prepared in good faith without prejudice to any or all parties concerned.

3. VESSEL PARTICULARS

The Dive Support Vessel (DSV) DP 2 ‘Fugro Saltire’ is a purpose built, deep water ROV vessel. It is equipped with a 150Te AHC knuckle-boom crane designed to deploy full rated load to 3000m (single fall) plus a separate 10T auxiliary subsea crane with 1,000m fall. 150T line fully equipped with man riding capability to SWL 15T Two Fugro FCV3000 150HP ROV systems are deployed via hydraulically operated doors on either side of the integrated ROV hangar via purpose built Heave Compensated (AHC) Launch & Recovery Systems (LARS) designed to minimize the effects of vessel motion. There is also the option of mobilizing a Lynx OBSROV system onto the back deck of the vessel. A working moonpool measuring 7.2 x 7.2m is situated immediately aft of the hanger area overlooked by a large Deck Operations Room. The full reach of the 46m x 22m timbered main deck is designed for deck loading of 10T/m2 and offers the flexibility to both carry substantial construction spreads and deck cargos and provide a platform with excellent seakeeping allowing the deployment of substantial subsea loads using the 150T main crane. Dimensions LOA 111.00m; LBP 100.20m Breadth 24.00m Draught 7.5m (maximum); 6m (50%DW) Machinery Main Power Plant 4 x Rolls Royce Bergen Diesel each driving Marelli Generators Total Power 15,750 kW / 16.800 kVA, 60Hz Auxiliary 1 x Mitsubishi/Stamford, 685kVA Main Propulsion Diesel-Electric : 2 x ducted CPP main propellers with variable frequency electric drive, Bow thrusters 2 x Tunnel; Super Silent, variable pitch, 1 x Retractable Azimuth, variable pitch, Stern thrusters 2 x Tunnel pitch controlled Speed Service 16 knots Endurance 60-90 days Deck/Machinery Deck area 1030m² , nominal Free timbered area : 960m² Deck loading 10T/m² throughout Deck crane Hydramarine 150T AHC, man riding capability to SWL 15T Single Fall Hook Travel: 3000m Load Capacities (SWL): 150Te @ 10m ; 75Te @ 20m ; 25Te@35m Whip Line (Aux Winch) : 10Te @ 36m ; Hook Travel : 450m Auxiliary crane Hydramarine 10Te @ 15m ; Hook Travel : 1000m Subsea Helideck Type Sikorsky S61 / S92 D-Value : 22.2m (22.2m Diameter); Max. landing load : 12,800kg; Control and Navigation DP system Simrad Dual Redundant K-POS DPII Dual DGPS; DPS 200 1 x Fugro Starpack DGPS DP references 2 x HiPAP500, Fanbeam, Seapath 200, RADius Communications Satellite Dual KU-Band / C-Band systems Max Capacity 2.5Mbit/s (KU, N.Sea) MF/HF Furuno FS 2570 VHF Furuno FM 8800S / FM 2721
