Diverless Sub - Sea Decommissioning Vessel

The Managing Director of Laslett International played a central role in navigating a dispute related to the engineering and construction of two cutting-edge Diverless Sub-Sea Decommissioning Vessels (DSDV).

These dynamically positioned subsea vessels were purposefully designed to cater to the offshore oil and gas sector's unique demands. Their versatility extends across a spectrum of vital offshore industry support functions, encompassing:

• Subsea Installation

• Construction Support

• Inspection, Repair & Maintenance (IRM)

• Subsea Structures and Pipelines

• Decommissioning Projects

These specialized vessels particularly shine in facilitating decommissioning efforts, a context where challenges often emerge, especially in tasks like Well Plugging and Abandonment. These activities must uphold safety and environmental standards rigorously.

The core objective is to meticulously isolate reservoir fluids from the seabed and surface, necessitating uncompromising technical integrity. The intricacies might involve interventions requiring the removal of down-hole equipment. Additionally, subsea wellheads must be extracted from their seabed locations.

In line with the decommissioning process, there arises the need to remove associated well flow-lines and control umbilicals responsible for wellhead operation. The process demands meticulous attention to detail, including the careful purging of flow-lines and hydraulic umbilicals to prevent any inadvertent loss of hydrocarbons associated with these systems.
