Chapter 18 of the Plan on Insurance of Mobile Offshore Units (MOUs) was substantially amended in the 2013 Nordic Plan. In the 2016 Version a new Section 6 on construction risks was added, and Section 5 on war risks was expanded by incorporating all clauses from Chapter 15, amended as appropriate to fit war risks insurance for MOUs.
By incorporating Chapters 10–14 on Hull- and Total loss insurances into Section 2 and 3 of Chapter 18 and Chapter 16 on Loss of Hire insurance into Section 4 of Chapter 18 of the Plan in 2013, Chapter 15 into Section 5 of Chapter 18 of the Plan and adding a new Section 6 on construction risks to Chapter 18 of the Plan in 2016, the intention that Chapter 18 contains all clauses relevant to MOUs was completed. There are no longer any cross references to any other parts of the Plan except to Part One, which according to the express provision of Cl. 18-1 also constitutes the “background law” for insurance of MOUs unless specifically amended by Cl. 18-1.
Thus, the applicable Loss of Hire Clauses for MOUs are found in Section 4 of Chapter 18 of the Plan (Clauses 18-43 to 18-56). Many of these Clauses are identical to the corresponding Clauses in Chapter 16 of the Plan. The Commentary to these Clauses are, therefore, limited to saying just that and referring to the Commentary to the equivalent clause in Chapter 16 of the Plan. Those Clauses that are only edited to fit to MOU terminology without any substantive amendment, are not commented on here.
There are two Clauses, Cl. 18-54 Simultaneous works and Cl. 18-55 Loss of time after completion of repairs that were substantively amended. Cl. 18-54 will be dealt with in 18.2 and Cl. 18-55 in 18.3 below.
