Our

Services

Calypso services include any assessment required for a jack-up to perform planned operations at any specific site. Assessments are reported through engineering reports and summary reports.
All our reports stand out through readability and clarity. Each report is directly suitable for use on-board and on-shore as well as for third party review and verification. A dedicated Captain’s summary provides a single-page, tabulated and illustrated overview of any report.
‍
The Calypso team stands out through responsiveness throughout the project. Our clients have become used to same day response to any request. Quotations and report revisions are typically delivered within 24 hours. There is always an engineer available to join meetings and support the crew on-board.

Going-on-location (GoL) and transit

A jack-up spends part of the time floating during transit. Her motions and stability should be within allowable limits. Calypso performs analysis to ensure this. When on location, the legs are lowered to make first contact with the seabed until the jack-up is soft-pinned. This transition is referred to as going-on-location and is typically the most weather-restricted operation. Calypso performs going-on-location analysis to determine the sea state limits.

Sea state limits depend upon the relative wave heading and the wave period. To account for these dependencies and to make the allowable significant wave height calculation accessible, Calypso presents values suitable for use with the Nereon Compass, a maritime weather forecast interpretation aid.

Leg Penetration Analysis (LPA) and installation

A jack-up gradually increases pressure on her spudcans, first with the hull in the water, then with the hull just above the waterline. The pressure increase is called preloading or pre-driving. A leg Penetration Analysis (LPA) provides preloading guidance, indicates risks and shows the expected penetration resistance. Leg Extraction Analysis (LEA) determines risks and operational guidance for the opposite process. Calypso further provides detailed geotechnical risks assessment and support in case of punch-through events.

All Calypso engineers are trained and licensed to come on board and support jacking operations. Typical responsibilities include determination of workability, preparation of MOC documentation, guidance on jacking operations and stability and assessment of RPD. Calypso engineers on board maintain direct communication with the Calypso team to perform analysis on the fly.

Site-Specific Assessment (SSA) and elevated operations

After preloading and jacking to operational airgap, elevated operations may commence. Calypso determines the allowable operational parameters and sea state limitations. A separate analysis is performed for storm survival. Operations and storm survival are addressed together in a Site-Specific Assessment (SSA). An SSA includes an LPA and is delivered as an integrated report.

Calypso performs further consultancy work, monitoring campaigns and RPD tolerance assessments for projects that require additional analysis.
