Case Study - Firenze FPSO Installation and Hook-Up Support

SAIPEM FIRENZE FPSO INSTALLATION AND HOOK-UP SUPPORT

SITE DETAILS:

Location: Aquila Field

Region: Adriatic Sea, Italy

Water Depth: 815 mtrs

FPSO: FIRENZE

SYNOPSIS:

To provide Marine and Positioning Services during installation and hook up of the Firenze FPSO at the Aquila field offshore Brindisi, Italy. Mobilisation and dimensional control measurements were done in the Dubai dockyard. InterMoor Marine and Surveyor Personnel were on board during the installation and hook-up to ensure the operation was carried out properly and safely.

WORK SCOPE:

Preparation of marine procedures and survey/positioning procedures, selection and auditing of support vessels, marine representation, positioning equipment mobilisation, dimensional control for positioning operations, surface positioning operations during installation and hook-up. InterMoor mobilized navigation equipment for the FPSO, three heading control tugs (HCT), a diving support vessel (DSV) and an offshore construction vessel (OCV). InterMoor also procured FPSO aft and forward towing equipment and provided tow masters and surveyors for the offshore operation.

CHALLENGES:

The tolerances for position and movement during the initial stage of the mooring were very tight. This required thorough knowledge and experience to develop the proper procedures and to control the marine operations offshore.

SOLUTION:

The marine and positioning solution was perfectly integrated as InterMoor offers both as combined. The surveyors could advise the mariners with very short communication lines and the positioning solution was optimized for performance while minimizing cost.

CONCLUSION:

The FPSO Firenze was installed in minimum time given the weather and operational challenges. InterMoor saved the client Saipem considerable money by covering marine and positioning services as integrated package reducing interfaces, administration and communication requirements.
