Use this category only for vessels identified as tankers in a reliable source such as Equasis or Marine Traffic.

Identify that source when copying data from it to the Description field when uploading.

Chemical and Product Tankers

Crude oil tankers

..... Note that the site Category Admin for Tankers believes that Equasis is notorious in classifying many products tankers (i.e. there cargo compartments are coated to be able to carry lighter products such as gasoline and naphtha) as crude oil tankers, taking over the definition from IHS/Fairplay which calls them crude oil/products tankers. Equasis subsequently cuts of the second part of the definition and uses the crude oil part only.

This results that in many times photos are allocated to the crude oil category, which in reality should be under product tankers. It is a time consuming effort to check each shot all the time.

4. Site
standards for all categories


We have site standards to ensure that the Shipspotting site maintains its focus on good images of ships themselves. In addition to these general standards, some categories have specific variations. Please use the Forum to raise any queries, or contact us at [email protected]

1. Size of image: The resolution must be between 768 x 1024 (or 1024x768) pixels and 10000 x 10000 pixels, files have to be jpeg format. Please make sure that the size you select to post will show a photo that is sharp at the maximum size it will visible on the site. Members should be constantly aware of the limitations of their cameras. Preferably the aspect ratio (width x height) should not be below 3 to 1, to give a view that corresponds to the dimensions of normal screens (viewfinder or computer).

2. Sharpness: Images must be sharp. In a sharp image, names, windows, cranes and other ship details will be clear. Moderate digital enhancement for sharpness is acceptable, but the image must remain sharp in at least one of medium/full screen/original sizes on a screen of at least 280mm. It is accepted that older images, processed from prints, negatives or transparencies may not be as sharp as modern digital photographs, although also in may cases digital photographs will benefit from sharpening

3. Exposure: All images should be appropriately exposed to show the ship clearly, and without large white or black areas. Silhouettes are not accepted.

4. Level: The horizon must be level and verticals should appear so. The image should be straightened where necessary. Some inclination for verticals at the edges of a photo can be allowed.

5. Distortion and enhancement: Photos taken with fish eye or other lenses that produce distorted images are not allowed. Black-and-white images are accepted only if that was the original medium; similarly for colour images. All manipulation of digital images should maintain a “natural” contrast and colour. For further guidance on digital enhancement see

6. Full ships only: For all views except those specifically for part-ship categories, bows, sterns and masts should not be cropped. Bow and stern shots are acceptable if they show the vessel from the waterline to the top of the superstructure.

7. Obstructions: Foreground obstructions should not restrict the view of the ship. Equipment and other vessels that are associated with the normal working of the ship (such as container cranes, tugs or bunkering barges) are acceptable provided they do not dominate the image. For ships alongside quays, the whole length of the ship should be in sight.

8. Main subject: The ship must be the main subject. Distant views where the ship is a small part of the image are not accepted.

9. People: The incidental presence of crew, passengers or shore workers in normal activity (ie not posed) is acceptable. Photographs showing people in the foreground, or others that may invade personal privacy, are not permitted.

10. Borders and watermarks: New digital images should not have added borders. Scanned historic images may retain a border provided it is unobtrusive and not decorative. Watermarks are acceptable provided they are discreet and do not impinge on the ship image. QR electronic codes are not permitted.

11. Small boats: Unless in use by the shipping or fishing industries or public authorities, small boats of less than 20 metres/65 feet in length are not accepted.

12. Multiple photos: When posting multiple photos of the same vessel taken on the same Date, the submission must be restricted to a maximum of 4 photographs with a significant change of Aspect/Angle between the photographs.

13. Date and location of photo: These must be included in the Description, if not added from the Location and Date of photo menus on the Upload page.

14 Old photos or negative scans from members archives must comply with Site Standards. Scratches or other blemishes should be removed, which may require the use of more advanced software.
