Provision of Rig Move Procedures

We'll get you moving safely and efficiently.

Viking SeaTech has the expertise and detailed knowledge to ensure a safe and effective execution and methodology for all marine operations included in scoping rig move procedures. From initial analysis to full-scale deployment, your operation can be made more efficient with the help of Viking Seatech. For a more detailed description of our procedures, see below. 

Installation Procedure

Upon completion of your mooring analysis, an installation procedure is prepared, outlining the operational steps required to install the mooring system. A dedicated procedure is prepared by competent personnel to suit the specific project requirements. The installation procedure covers all operational aspects, defining points of contact, recommended working practices, vessel requirements and sequence of events.

The document is distributed to all personnel involved in the operation. In case operations deviate from the defined procedure, a management of change form is completed by designated Viking SeaTech personnel on board the vessel. The main purpose of this procedure is to ensure a safe operation, mitigating risks to personnel and assets. It also ensures the effective planning, mobilisation, execution, verification and demobilisation of operations. All required mooring components are listed in the document, alongside the specific characteristics. Drawings of all system components are also provided.

As with all Viking Seatech operations, safety is paramount. So the maximum environmental conditions for the safe execution of the work are defined and a risk assessment is carried out with the aim of identifying risks and implementing mitigation measures. Within this procedure, the sequence of events to be followed prior to the deployment of an anchor is illustrated. The anchor deployment sequence is thoroughly explained and illustrated. Calculations are carried out to determine the required vessel payouts, required bollard pull tension and bearings. These procedures also cover the sequence of events to be followed in the unlike event of anchor slippage.

The whole installation is carried out in compliance with the relevant codes and statutory requirements.

Recovery Procedure

Upon completion of the drilling activities, the mooring system is recovered as specified in the recovery procedure. This is prepared by highly competent personnel to suit the specific project requirements with a detailed outline of the sequence of events. All operational aspects, defining points of contact, recommended working practices, vessel requirements and sequence of events are covered in the recovery procedure.

This document is also distributed to all personnel in the operation. To ensure operations do not deviate from the one specified, designated Viking SeaTech personnel on board the vessel will complete a management of change form. This will ensure a safe operation, mitigating risks to personnel and assets. It will also complement planning, mobilisation, execution, verification and demobilisation operations. The maximum environmental conditions for the safe execution of the work are defined and a risk assessment is carried out with the aim of identifying risks and implementing mitigation measures.

The procedure will incorporate a step-by-step description of the line recovery sequence. It is reviewed by the marine personnel in conjunction with line configuration drawings. Calculations are carried out to determine the required bollard pull and positions of the vessel at each relevant stage. And for additional clarification, graphical representation of key operational steps is provided.
