I’ve been thinking about the same since I saw your comment. I think a comma after Tobago: “Trinidad and Tobago, and in Suriname” would make the sentence easier to understand but it also might add meaning that isn’t there. Does the added comma imply that primary object (most of the work) was done on Trinidad and Tobago, while the work in Suriname is smaller or less important?
