Gold Course In theory, the determination of laytime and demurrage in tankers, if incurred, is a straightforward process as all of the relevant terms and clauses are contained in the charter party. However, as anyone who has examined a charter party will be only too well aware the wording is often less than clear and consequently the meaning is obscure. In short, lack of clarity over what does and does not count as used laytime can lead to contentious issues between parties. One of two things then happens. Either, a claim is made which potentially can require substantial resources to pursue, both in terms of time and money. Alternatively, potential claims are left to accumulate, unattended and considerable sums of money go begging.

There are no pre-requisites for this course, nor is any advanced preparation required.

This is a two day course.

Through a series of presentations and workshops the objectives of this course are:

  • To help understanding of the commercial risks associated with laytime and demurrage in shipping charter parties and oil sales/supply agreements and the problems of ensuring compatibility between the two contracts;
  • To help minimise these commercial risks;
  • To clarify some of the most important issues surrounding laytime and demurrage;
  • To provide practical examples of where things can go wrong and how such events might be avoided;
  • To help improve the efficiency and speed of claims handling to the benefit of the parties concerned.

The aim is to provide practical understanding and instruction in the complexities of laytime and demurrage and in so doing, de-mystify them. Emphasis is placed on how to avoid potential problems from the outset, how to limit risk and exposure and ultimately save money through the efficient handling of claims and avoidance of costly legal proceedings. The course highlights differences between major charter parties and the problems encountered between shipping and oil sales contracts.

This is offered as both a public course and in-house training programme. In-house programmes enable client companies, if they wish, to select actual examples from their own operations for use in case studies.

The course is presented in association with Richardson Lawrie Associates Ltd (RLA) - a maritime economics and business consulting firm with an extensive global practice in oil, gas and chemicals transportation. For many years, RLA has been presenting management training programmes and workshops in all aspects of oil, gas and chemicals transportation around the world.

There are no pre-requisites for this course, nor is any advanced preparation required.

This is a two day course.
