Win tenders with MO4

Tendering is always a stressful process: there never seems to be enough time and budget to do the work the way you would like to. Further, a lot of things are still unclear. However, it is extremely important, as it lays the foundation of the project and the companies’ project pipeline of works. Important aspects […]

Pandora’s box: Hs & Tp

Let me start this post with the statement that I’m not an oceanographer nor a meteorologist. I’m an engineer with a background in hydrodynamics, who rely strongly on input from the ocean side. So I might cut a few corners here and there. In this post I would look like to bring up what is […]

Diving deeper into cable lay engineering

It was my intention to write only two blogs on cable lay, but here’s the third one. There’s a lot of interesting stuff to investigate. We’ve only touched upon regular lay, maybe we’ll dive into pull-ins later as well. In the last blog post we’ve looked at cable response due to vertical chute motions. It […]

Cable lay engineering

In cable lay analysis the response of offshore power cables to a vessel exposed to waves and currents is investigated. We’ve already touched upon this subject in a previous blog, stating that cables are delicate and easily damaged. Especially the motions of the vessel have a strong influence on what tensions (positive or negative) and […]

Forecasting jack-up barge motions

The first jack-up platform was built in 1950, and since then these barges have been used extensively in the offshore industry. Most often they were used as a stable drilling platform (MODU). At present jack-up platforms are involved in the construction and maintenance of offshore wind farms as well. The rules that are commonly applied […]

Forecasting DP footprint

Station keeping is required for many offshore operations, for instance when transferring crew with a gangway, but also for drilling, dredging and pipe or cable laying. Increasingly, these operations are performed with vessels on dynamic positioning (DP) due to its advantages for mobility and for operating in deeper water. A vessel operating on DP is […]

Blog post Cable lay

This blog post concerns the engineering aspect of subsea power cable installation operations. It consists of two parts: the first provides basic information regarding cable installation and the second provides a solution to significantly lower risks associated with installation. A power cable is a delicate and crucial element of an offshore wind farm. Inter array […]

How can the industry help?

According to the World Shipping Council last year 1390 containers fell overboard due to different circumstances. But when the MSC Zoe lost 291 containers just north of the world heritage area of the Wadden sea in the Netherlands on January 2nd  a natural disaster was born. Hundreds of volunteers and the national army are working […]

Workability requirements in offshore contracts

The challenges in the current offshore market are still in full swing. The price of oil has recently taken a new plunge and the offshore renewable industry is under pressure to cut costs as it is moving away from government funding. The market conditions for many offshore operators remain demanding. Recent commercial contracts awarded for […]
